Garbage disposal unit. A garbage disposal unit (also known as a waste disposal unit, food waste disposer (FWD), in-sink macerator, garbage disposer, or garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The device shreds food waste into pieces small enough—generally ...

This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste can either be solid, liquid, or gases and each type has different methods of disposal and management.

SYBR Green I (SG) is an asymmetrical cyanine dye [1] used as a nucleic acid stain in molecular biology. The SYBR family of dyes is produced by Molecular Probes Inc., now owned by Thermo Fisher Scientific. SYBR Green I binds to DNA. The resulting DNA-dye-complex best absorbs 497 nanometer blue light (λ max = 497 nm) and emits green light (λ ...

[13] A waste collection and resource recovery system was established around the 'dust-yards'. Main constituent of municipal waste was the coal ash (‘dust’) which had a market value for brick-making and as a soil improver.

Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom.
